标准摘要
[中文适用范围]： 该程序适用的浓度至少为 30 mg/m3，采样周期通常为 30 分钟。 当质量浓度大于 2 000 mg/m3 时，通过采样装置的待调查废气体积为 30 升。 给出了已知对滴定读数有影响的物质。 所有浓度均基于温度为 273.1 K、压力为 101.3 kPa 的干燥气体。 [外文原描述]： The procedure is applicable from a minimum of 30 mg/m3 by reference to sampling periods of mormally 30 min. At mass concentrations greater than 2 000 mg/m3 the volume of the waste gas under investigation passed through the sampling train is 30 litres. Substances, which are known to have an effect on the titration reading are given. All concentrations are based on dry gas at a temperature of 273,1 K and a pressure of 101,3 kPa.
